  2. Butter a gratin dish.

  3. Mix breadcrumbs, parsley, herbs, salt, and pepper in a bowl.

Assemble

  1. Sprinkle the breadcrumb mixture over the butter in the dish and moisten with white wine.

  2. Open the oysters, remove the gills, and place them in the dish, pouring the oyster juice over them.

  3. Cover the oysters with more breadcrumbs and dot with butter.

Bake and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oysters
Provide the main flavour and tender body that the crumb topping surrounds.
Breadcrumbs
Form a crisp, golden topping and absorb the wine and oyster juice.
Butter
Adds richness and helps the crumbs brown in the oven.
White wine
Moistens the crumbs and adds acidity that balances the rich butter.

The step that matters

Open the oysters, remove the gills, and place them in the dish, pouring the oyster juice over them.. Keeping the oyster juice in the dish keeps the oysters moist as they heat. Overcooking makes oysters tough and shrinks them, so they need only a short bake.

Swap the parsley

How well each one fits the dish's main ingredients (oyster, butter, pepper, white wine):

  1. Thymefits about as well
  2. Parsleythe original
  3. Tarragonfits about as well
  4. Marjoramfits less well

Fit is the average pairing score against oyster, butter, pepper, white wine. Candidates are from the same food group and used in at least 100 recipes.
